Springs due to Stiffness Simply Supported by Fictitious Column, Assuming Elastic Surface Foundation and Considering Shear Stiffness

These formulas are used to calculate the spring constants of the stiffness using a fictitious column for a simply supported column, taking into account the shear stiffness.

C_{u X} = \frac{12 \cdot E I_{Z}}{H^{3} \cdot A_{h e a d} \cdot (4 + k_{z})}; C_{u Y} = \frac{12 \cdot E I_{Y}}{H^{3} \cdot A_{h e a d} \cdot (4 + k_{y})}; C_{u Z} = \frac{E \cdot A}{h \cdot A_{h e a d}}

C_{φ y} = \frac{E \cdot I_{z}}{A_{h e a d} \cdot h} \cdot \frac{2}{1 + k_{z}}; C_{φ X} = \frac{E \cdot I_{y}}{A_{h e a d} \cdot h} \cdot \frac{2}{1 + k_{y}}
